Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed April 28, 1905- Serial No. 257,842.

To all whom it mag. concern:

Be it known that we, BENJIMAN N. BER- MAN and ABRAHAM H RRIs, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in lBunching-Machines for Making Cigars, of which the following is a specification.

Our invention has reference to bunchingmachines for making cigars; and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of our invention is to provide a suitable construction of bunching-machine adapted to be operated by hand, whereby the operator may bunch the tobacco preliminary to being placed in the Wrapper and by which the operation may be more satisfactorily performed to insure the requisite shape required without danger of making the filler too dense for proper smoking.

Our object is also to provide the machine with adjustable capacity whereby differentshaped fillers may be made as desired.

Our invention consists of a die of elastic or yielding material combined with an apron above 1t and in which the tobacco filler is placed and a swinging arm having a roller for operating upon the apron and adapted to swing closely over the die; also, in having the swinging arm pivoted and formed with an adjustable end by which the roller may be supported at various angles to the surface of the Y chine embodying our improvements.

die; further, in having the axis of the roller adjustable verticallyto vary the position vertically relatively to the upper surface of the die.

Our invention also comprehends details of construction, which, together with the features above specified, will be better understood by reference to the drawings, in which Figure 1 is a plan view of a bunching-ma- Fig. 2 is a sectional elevation of same on line 2 2 of Fig. 1. Fig. 3 is a section of Fig. 1 on line 3 3, and Fig. 4 is an end view of the roller-shaft and supporting-arm with part in section.

A is the table or bench, only a portion of which is shown. Usually each machine comprises a small table with the appliances here shown but it is evident that a series of these appliances may be arranged side by side upon a long bench.

B is a segmental die, preferably of rubber or other yielding or elastic material, and has the recess B near the forward end. It is secured to the table A bythe end clamps C O. The rear clamp Cis extended to form a groove C to receive the cigar-filler after the same has been rolled and compressed.

D is the apron and may be made of oilcloth, leather, &c., and has its ends secured to the clamp-plates O C by the clamping-bars c c, the length of the apron being considerably longer than the length of the die B, whereby it may be formed into a reverse loop to pass about the tobacco filler S and also the roller E. j

The roller E is loosely j ournaled on the shaft F, terminating in the ball-handle F at its free end and having the other end'adjustably clamped to a swinging arm of special construction. The swinging arm J is journaled upon the downwardly-extending pin L,

. secured to the bottom of the table or bench A,

and is supported upon antifriction-balls N,

carried upon the head M. To the free endof the arm J is hinged at K the bell-crank arm H H, the part H being adjustable between the adjusting-sorews I I on the arm J and the part H being extended upward through a slot P in the table and forming a support for the shaft F of the roller E. This shaft extends through a vertical slot h in the part H and is adjustable vertically therein, being clamped in place by the nut G. The curvature of the slot P and die B are made with the shaft L at the center, as will be obvious from Fig. 1.

We do not confine ourselves to any form of adjustment between the arm H and the swinging arm J, that shown being one form which We have found well suited to the purposes of our invention.

The roller E is preferably made tapering, so that the outer end will have a surface speed commensurate with the increased length of the apron at the outer or right-hand edge over the length at the other or left-hand edge. This also, with the arm H arranged vertical, gives an obliquity to the roller, as shown in Fig. 2, to form a tapering spacebetween it and the die which corresponds to the taper to be given to the filler. This obliquity of the roller may be increased or decreased by ad justing the arm H, which may be accomplished by the screws I I.

The operation will now be understood. The roller E is moved to the right, Fig. 3, as far as it will go. The tobacco filler is then placed upon the apron, crowding it down into the groove or recess B. The roller is then moved over the die, which action folds the apron over the fillers, as shown in Fig. 3. By continuing the roller as far to the left in Fig. 3 as it will go the compressed filler is rolled into the receiver C. The elasticity of the rubber die B forms a yielding bed upon which the rolling of the filler is done, and should the filler tend to be rolled too hard the die gives and prevents the compression from being too tightly done. These features enable an operator to perform good work all the time and with less care and risk.

If desired, the head M may be adjusted vertically by the set-screw m; but ordinarily the adjustment secured at h in the arm H will be found amply sufficient.

We do not limit ourselves to the details, as these may be varied without departing from the spirit of the invention.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a bunching-machine, the combination of a die of yielding material, a loose apron having its ends secured adjacent to the ends of the die, a swinging arm pivoted to a support to one side of the die and having at its free end an adjustable part hinged to the arm on an axis in the plane of movement of the swinging arm and provided with a laterally-extending shaft, and a roller journaled upon said shaft and arranged between the apron and die, the construction being such that the vertical obliquity of the roller may be varied through the adjustable part on the end of the pivoted swinging arm.

2. In a bunching-machine, the combination of a die, a loose apron having its ends secured adjacent to the ends of the die, a pivoted swinging arm pivoted below the die and having an upwardly-arranged arm extending above the die and provided with a slot, a laterally-extending and overhanging transverse shaft arranged above the die and ad justably clamped in the slot of the upright arm to provide vertical adjustment, and a roller carried by the said shaft and arranged between the apron and the die.
